A frit is defined as a porous filter made from bonded grains of quartz glass. Our custom quartz frit discs are manufactured from the same high purity raw material as our tubing and rod. These chemical resistant frit filters are used in many applications such as filtration of liquids or corrosive gas, heat diffusion, and flow regulation. They are ideal for chemically inert and high purity uses.
We also provide chemical-resistant lab trays and clear fused silica plates for specialized laboratory and industrial applications that demand durability and purity.
Our product range includes quartz microscope slides, crafted from high purity quartz to ensure precision and durability. With our reliable custom quartz frit discs and chemical resistant frit filters, we deliver consistent performance in environments where purity and chemical resistance are critical.

Porosity
Choosing the correct porosity is key for success in working with glass filters. These frits vary in porosity according to grades that are expressed as 00, 0, 1, 2, 3, and 4. The table below shows the various fields of application for each grade of porosity. The pore size indicates the largest pore in the disc, as well as the diameter of the smallest particle retained during filtration.
